Vuls is an agentless vulnerability scanner written in golang.
It can scan localhost or remote hosts via SSH. Vuls has a Terminal-Based User
Interface(TUI) to display the scan results.

Vuls' features include:
- scan for vulnerabilitie in Ubuntu, Debian, CentOS, Amazon Linux, RHEL, Oracle
  Linux, FreeBSD and Raspbian;
- scan middleware that are not included in OS package management;
- nondestructive testing;
- email and slack notification.

Vuls uses the port security/go-cve-dictionary to look up information about
packages' CVEs. Install that port separately somewhere in your infrastructure
and point to it for CVE queries.
